Abstract :
Roots are crucial for plant growth and development but, so far, their beneficial qualities have not been used in genetic engineering strategies. To exploit this missed opportunity, a thorough understanding is required of the genetic mechanisms that control gene expression in response to different cues. A global map of gene expression for the Arabidopsis root has recently been published that consists of high-resolution spatial- and temporal-expression profiles. This new dataset will be a valuable starting point for understanding the hidden organ of plants.
